Description
技术领域
本申请涉及分子生物学和生物技术领域,特别是涉及一种拟茎点霉的原生质体制备方法及基因敲除方法。
背景技术
内生真菌枫香拟茎点霉是一种广谱内生真菌,能与多种植物共生(Yang B, etal., Plant Physiol Biochem. 2014, 82:172-82),如小麦、水稻、花生等。前期研究表明,该菌在低氮条件下,可促进氮素积累,增强氮素代谢关键酶活力,从而有利于植株氮素营养的吸收,提高氮肥利用率和植株总生物量(Yang B,et al., Front Microbiol. 2015,6:982);还能够促进花生结瘤增产(Zhang W, et al., Plant Physiol Biochem. 2016 ,98:1-11)。转录水平研究表明,该菌在共生状态时,其苯丙氨酸、酪氨酸、色氨酸合成相关基因明显上调 (Zhou J,et al., Front Plant Sci. 2017,8:121),而这三种氨基酸是多种次级代谢产物的前体物质,在生长、再生,防御和环境响应等方面具有重要作用 (Maeda H,Dudareva N. Annu Rev Plant Biol. 2012, 63, 73–105)。抑菌实验研究发现,该菌能够抑制尖孢镰刀菌的生长,而尖孢镰刀菌是引起小麦赤霉病的重要病原病之一。目前防治植物病害的主要策略是采用化学试剂 (Figueroa M, et al., Mol Plant Pathol. 2017,doi: 10.1111/mpp.12618; 张洁,et al., 小麦赤霉病的防治技术研究进展.中国植保导刊. 2014,34(1):24-28,53),如拜耳的戊唑醇、丙硫菌唑以及丙硫菌唑与氟吡菌酰胺复合制剂,巴斯夫的多菌灵、甲基硫菌灵、三唑酮、戊唑醇、咪鲜胺、井冈霉素等。市面上较为通用的药剂有戊唑醇与咪鲜胺的混剂以及氰烯菌酯的相关混剂产品。我国防治小麦赤霉病常用多菌灵。多菌灵能够刺激病菌产生DON毒素,尤其是使得抗药性菌株产毒能力更强 (ZhangL, et al., Mol Plant Pathol. 2016,17(1):16-28)。抗药性的产生,使得无论使用什么药剂,很难起到防治作用。除此之外,药剂的大量使用还会造成环境污染和食品安全问题。其次,防治植物病害最经济有效的措施是选用抗病品种。国内育种工作者在选育和推广抗病品种方面做了大量工作,但总体而言其抗病性和丰产性还不够理想 (Giancaspro A, etal., Front Plant Sci. 2016,7:1381)。植物转基因品种可以提高植物的抗病性,但是植物转基因品种的生物安全性备受争议 (Devos Y, et al., 2014,23(1): 1-25),使得植物转基因品种的应用十分受限。枫香拟茎点霉在植物中的定殖不进入种子,具有良好的生物安全性,避免了植物转基因带来的争议问题,为开发新型的农业生防菌剂提供支撑。近年来研究表明,内生真菌次级代谢产物不仅揭示了内生真菌在与植物的互惠共生中的重要作用,而且可保护植物免受生物胁迫和非生物胁迫损伤 (Panaccione DG, et al., PNAS.2001, 98,12820–12825)。Lahrmann等发现内生真菌次级代谢产物是维护互惠互利的主要决定因素 (Lahrmann U,et al., PNAS. 2013,110,13965–13970)。因此,内生真菌枫香拟茎点霉与植物良好的互惠共生关系机制的研究,使得其遗传操作体系的构建显得尤为重要。迄今为止,该菌的遗传操作体系的研究及应用尚属空白。本发明旨在提供适合在枫香拟茎点霉中使用的遗传操作体系。
枫香拟茎点霉为丝状真菌,而丝状真菌遗传背景较细菌和酵母而言,更加复杂,遗传操作困难,也导致丝状真菌的分子生物学和遗传学研究进展相对缓慢。对丝状真菌进行基因敲除、敲入或阻断的限制因素主要有四个方面:(1)原生质体制备较困难;(2)同源重组效率低,例如在烟曲霉中同源重组效率低于5%;(3)可使用的筛选标记有限,目前丝状真菌主要使用的抗生素筛选标记有3种:潮霉素、草丁膦和博莱霉素等,而且有限的筛选标记并不是对所有的丝状真菌都起作用;(4)RNA干扰技术不能完全消除基因的背景影响,并且在一些丝状真菌中很难建立有效的RNA干扰系统 (李红花,刘钢. 遗传. 2017, 39(5): 355-367)。本发明提供了该菌的原生质体制备技术、转化及基因敲除技术,为解析这个独特菌株的遗传背景和深入研究枫香拟茎点霉与植物共生,次级代谢产物生物合成对植物的抗病性研究创造必要条件。

本实验说明ura基因敲除菌株的分子鉴定过程:
倒置培养2-3天后挑选转化子单菌落提取基因组DNA,左右臂向外各延伸约100 bp后分别设计上下游引物,以转化子基因组DNA为模板扩增靶点处DNA片段,琼脂糖电泳鉴定。基因成功被敲除的菌株电泳条带比未被敲除的菌株或野生型菌株电泳条带大1.4 kb,将成功敲除的电泳条带切下测序,比对测序结果最终确定基因是否被成功敲除。
实验结果如附图4所示。左侧为基因敲除时同源臂的设计原理示意图,右侧为PCR实验验证目标基因敲除前后所得到的目标片段大小,野生型基因片段约2200bp,目标基因敲除后片段大小为3600bp。
